Abstract

The invention relates to the technical field of frequency converters, and discloses a structure of a single-tube IGBT module frequency converter. The structure comprises a bottom shell box body with aventilation opening and a middle shell box body assembly embedded into the bottom shell box body. The middle shell box body assembly comprises a middle shell box body, a radiator, a fan, a rectifierbridge, a capacitor plate with a capacitor, a driving plate and an aluminum substrate assembly. The fan of the middle shell box body assembly is arranged at the position, corresponding to the ventilation opening, of the middle shell box body. The middle shell box body is provided with a first partition plate and a second partition plate which are arranged in the air duct direction of the fan. Therectifier bridge, the capacitor plate and the driving plate are fixedly connected and mounted on the middle shell box body. The structure has the advantage that the middle shell box body is divided into three internal spaces through the first partition plate and the second partition plate, the aluminum substrate is located in a windless channel, and the capacitor and the radiator are located in the air duct for heat dissipation and are isolated from each other. Meanwhile, compared with a traditional mounting process, the positioning is accurate, the production and assembly process is simple, and the production efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a structure of a single-tube IGBT module frequency converter. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The components used in the inverter unit are IGBT modules, and the IGBT modules are divided into integrated IGBT modules and single-tube IGBT modules. The integrated IGBT module integrates multiple single-tube IGBTs and braking and detection units into one package. The installation process of frequency converters using integrated IGBT modules is simple, but the cost is very expensive. The cost of inverters u...
